In the present study SPH method was applied in order to study the peculiar flow around a 2D flat planing surface. Results were compared with analytical solutions and RANSE calculations. For the application of the method to this particular case an SPH code with an inlet and an outlet of particles was developed.

In recent years an increasing interest towards innovative techniques to be applied in usual experimental facilities has grown. From cavitation tunnel point of view, attention has been given to measurement of dimensions of propeller cavitation bubbles. The need arises from the increase in ship performance and environmental/comfort requirements,...

This work deals with the application of different numerical methods for the evaluation of slamming loads on V-shape sections, namely a commercial CFD VOF program and Smoothed Particles Hydrodynamics Method (SPH) currently under development at DINAV; preliminary results from both methods are presented, together with a comparison between the two...

A free surface Reynolds-averaged Navier–Stokes solver and a smoothed particle hydrodynamics method, the latter currently under development by the authors, have been applied to the evaluation of slamming loads (global forces and local pressures) over a series of two-dimensional cases for which experimental data (drop tests with a free falling...

This paper relates to the comparison of two different numerical methods applied for the evaluation of slamming and sloshing problems. In particular, a CFD VOF program and Smoothed Particles Hydrodynamics (SPH) currently under development at DINAV have been applied.

Different numerical methods have been applied to the evaluation of slamming loads on a typical ship bow section, for which experimental data of drop tests has been made available within MARSTRUCT thematic network. Experimental data cover different drop cases, with variable speed and different heel angles. Numerical techniques adopted are a...

In present paper application of computer vision techniques to propeller cavitation experiments is presented. These techniques are widely adopted in many different environments and therefore they are well documented. They are also attractive from an economic point of view, due to relative low cost of the hardware involved. Nevertheless their...
